Besides the value of the land, many of the orchards are going out because they can not compete with the foreign (especially Chinese) apple growers. When I was a kid, I worked on a fruit farm for 9 years. All of the neighborhood kids worked there. Now you can't get a local to work on a farm (at least in the east). The farmers need to bring in their workers from Puerto Rico and the Dominican. They now have all of the environmental, immigration, OSHA, and labor laws to worry about. I'm not saying that those are bad things, but they definitely contribute with our inability to compete. Countries with much lower standard of living are not very interested in listening to our politicians talk about child labor and worker abuse, when they can double or triple their (meager) annual incomes.
Bill, I know exactly what you mean about North Texas... I used to Live in The Colony, Tx. when it was only 3-4,000 people (1978). I recently visited there when I was on a business trip to Dallas. I was flabbergasted with almost 40,000 people and all the malls. I'm glad I moved away before that happened.
